Dear Chrono Team,
I am currently implementing a simplified tractor model in Chrono for use in a real-time simulation environment. The model consists of a rigid chassis, a fixed rear axle with steered and driven wheels, and a front axle modeled as a rigid beam suspended via a central pivot (as commonly used in tractor front axles) with additional steering. The goal is to capture the essential dynamic behavior of the vehicle—particularly in heave, pitch, and roll—sufficiently well for deployment on a motion platform. The vehicle operates on a rigid, non-deformable terrain, represented by a tessellated triangular mesh. The primary excitation arises from terrain-induced vertical disturbances with dominant frequency components up to approximately 10 Hz. *My core question is:* What is the expected feasibility of running such a model in real time using Chrono? In particular: - Are there benchmarks or best practices for achieving stable simulation at control loop frequencies ~1 kHz? - Which solver/integrator is recommended for this type of setup? - Are there known performance bottlenecks when using non-deformable terrains modeled as triangular meshes? Any insights—especially from prior experience with real-time vehicle simulation or motion cueing applications—would be highly appreciated.
